Cannot add local imagery to toolbar

[Stereo]

What steps will reproduce the problem?

1. Open the map in Luxembourg
2. In the imagery menu, geoportail.lu ortho 2016 should appear. Spend your afternoon mapping.
3. In Preferences > Toolbar, in the right pane, open Imagery.

What is the expected result?

geoportail.lu ortho 2016 is shown and can be added to toolbar

What happens instead?

Only the default imagery layers can be selected.

Please provide any additional information below. Attach a screenshot if possible.

Workaround: closing and reopening the preferences seems to refresh the choices. The local imagery can then be added to the toolbar.
